It looks like you are trying to store a 250 character string into a 50 character buffer, and you have told the formatter that the buffer is only 3 characters long. But ultimately your code makes little sense.
One of these days I'm going to think of a really clever signature.

A description I read had GetLastError where I expected WSAGetLastError and my searches did not return those pages. Thanks for the links.
Thanks for your time

I think you meant to reply on the message thread below.

Even if make 50 char sting into a 50 char buffer, I am getting the same error.
Is there any other way to do this?
The same code works fine in VS6.0 and not in VS2008.

As I said before, you are specifying a buffer size of 3, so any number of characters greater than that will cause the error. Check the documentation[^] for specific details of the parameters and their values.

I am trying to guess what your code is supposed to do here but this might be closer to what you want:
char buffer[50]
int offset =3;
char Buffer[250];
sprintf_s(&buffer[offset], sizeof(buffer) - offset, "%s", Buffer);
The second parameter of sprintf_s as used here is the maximum allowed length of the output buffer. If the buffer is of size 50 and you want to write starting in element 3 then the obvious size remaining is 'sizeof(buffer) - offset' and not 'offset'.
